Product Description

 

Top Selling Power Transmission Line Equipment MOA ZnO Lightning Arrester 

 Characteristics: 
1. The Core column applied winding structure, Polymer Housed core pillar molded on the core column, 

with almost no internal air gap, and outstanding sealing performance Simple in structure, small in size 

and light in weight. 

2. Polymer Housed with silicone rubber, explosion-proof ZnO varistor as the core component is large

in flow capacity.

3. International standard IEC 60099-4 and ANSI 62.22, and with high reliability. With fully insulated tops,

the product can be applied to the complete cabinet installation, 

which can reduce the designing size of cabinet. 

4. Products with detachment device can provide signals for quitting operation when failure occurs,

avoiding arrester explosion, and it is maintenance-free. 
5. Polymer housed products with a six CTI level, creepage distance meets the requirements of IV level

in heavy pollution areas.
